CORER.

Application filed October 6, 1925. Serial No. 60,851.

This invention relates to corers, and more particularly to an apparatusfor quickly coring tomatoes, apples or other fruits, vegetables orarticles of any character in which it is common to remove the coreespecially when preserving, although of course the in* vention is notlimited to any particular use.

An object of the invention is to provide a corer which will not only cuta circular opening into the article but will also sever the core withinthe circular opening from the article and perform this work quickly andefliciently.

A further object of my invention is to provide an apparatus which willconstitute a time saver as well as one which will greatly improve thecoringfoperation, preventing the removal of unnecessary portionsthereo-f.

A' further object is to provide` an improved corer which embodiesvarious novel features of construction and 'combinations andarrangements of parts, all of which will hereinafter be more fullydescribed and pointed out in the claims.

In the accompanying drawings- Figure 1 is a view, mainly in elevationbut partly in longitudinal section, illustrating my improved corer; l

Figure 2 is a view in transverse section on the line 2-2 of Figure 1;

Figure 3 is a view in transverse section on the line 3 -3 of Figure 1;

Figure 4 is a view in end elevation of the corer. l

1' represents a supporting block which is Y recessed at its center asshown at 2 and provides a mountinv for a drive shaft 3 having a pulley 4or otlier device thereon to which motion is transmitted from any sourceof power. f

The apparatus illustrated is a double apparatus, or, in other words,includes a pair of corers arranged in tandem and driven from a singledrive shaft 3. As these corers are precisely alike in construction andoperation the detailed description hereinafter of one will apply aliketo both.

The drive shaft 3 above referred to projects into gear housings 4 atboth sides of recess 2 and has fixed thereon within the housings 4 gearwheels 5. Within each housing 4', preferably lbelow the drive shaft '3and parallelthere-with, 1 locate a second shaft 6 having suitablebearings within the block.

The shafts 6 do not extend across the recess 2, and each shaft 6 has agear wheel 7 fixed thereon which meshes with the gear wheels 5. Eachgear wheel 5 and 7 is relatively long so as to give great strength andrigidity to the meshing action and power transmission.

Hoods 8 are secured to the respective ends of the block 1, and thesehoods are open at their bottoms and are preferably secured to the blockby screws 9. Each hood 8 in its outer end is formed with an opening 10,and in line with this opening 10 a. skeleton head 11 is positionedwithin the hood and is connected by a tubular extension 12' with a disk13. This disk 13, extension 12 and head 11 preferably constitute anintegral piece, and an internal circular rack 14 is secured to the disk13 and is externally preferably of the same diameter as the disk.

A pinion 15 on drive shaft 3 meshes wit this internal rack- 14 tov turnit in a -dircction opposite to the direction of rotation of the shaft 6.A cover 16 is fixed to the shaft 6, preferably by a pin 17, and islocated within the head 11 and against the inner end of said head sothat it functions to hold the head and its assemblage in properoperative relationship to the other features of construction.

The forward or outer end of the head 11 is internally screw threaded, asshown at 17, to receive the screw threaded inner end of a rotarycircular cutter 18. This cutter 18 I refer to as a circular cutterbecause it is -circular in cross section; while it is preferably ofgeneral cylindrical form internally, it is of truncated conical ortapering form externally so that its outer extremity presents a sharpcutting edge 19, the latter being provided with notches 20 which assistin insuring a cutting action on the vegetable, fruit or other articlewitlr which it is engaged. An annular flange 22 is formed on the cutter18 and engages the end of head 11 so as to limit the movement of thehead relative to the cutter and permit the parts to be tightly boundtogether by their screw threaded action.

On the forward or outer end of the` shaft 6 a cutting blade 23 isprovided and this blade may constitute a fixed or integral part of-theshaft itself or may be a separate part, as desired. The blade 23projects laterally from the longitudinal axis of shaft 6 and has a sharpcutting end 2,4 and a sharp cut ting edge 25 at the side thereof.

"his blade 23 is suiiiciently Wide to project close to the inner face ofthe cutter 18 and is transversely of a suitable dimension to insure acomplete cutting of that port-ion of the core or article which isinserted or forced into the cutter 18.

Suitable grease cups 26 may be supported on the block 1 to supplylubricant to the Wheels and 7, and of course any suitable lubricatingmeans may be provided to reduce friction to a minimum.

.lt will be noted that the shaft 6 and the head 1l turn in the oppositedirection and at different speeds so that the shaft 6 With its cutting'blade 23'turns at a greater speed than the circular cutter 18. This isdue to the fact that mbtion is transmitted directly through the gears 5and -7 to shaft 6 While ,motion tothe head 11 is through the mediumofthe pinion 15 and the internal rack 14. j

Y The fruit or articleto be cored is forced onto the cutter 18 and asthe blade 23 revolves in the opposite direction it Will cut out the coreWithin the confines of the cutter 18 and do this Work rapidly,completely and Without injury to the fruit or other article.

As the cutter andthe blade turnin vopposite directions there will be'notendency to revolve the fruit or vegetable being cored As this fruit issometimes soft this is very important because if the critter and bladerevolved in th'e same direction it would have a tendency to turn theAfruit, which must herefore be 'held tightly in order to pr-eventI itsrevolving` and Will be` crushed or injuret. It is desirable to have theblade revolve more rapidly than the cutter as its Work of scooping orcutting' out the core can beI more efiiciently carried out if theproportion of the speed ofthe .parts is different as has been found byactual eztperiment; v

Various slight change and alterations might be made in the general formof the parts described Without departing from the invention and hence ldo not limit myself to the precise details-set forth but consider'myself at libertyl to make such slight changesand alterations as fairlyfall within` the spirit and scope of the appended claims.
